FFDShow is a DirectShow decoding filter for decompressing DivX, XviD,
H.264, FLV1, WMV, MPEG-1 and MPEG-2, MPEG-4 movies. It uses libavcodec
from ffmpeg project for video decompression, postprocessing code from
mplayer to enhance visual quality of low bitrate movies, and is based on
original DirectShow filter from XviD, which is GPL'ed educational
implementation of MPEG4 encoder.

First of all, the FFDSHOW
consumes way less CPU power than original DivX codecs, even with maximum
post-processing. At the same time the post-processing seems to give
excellent quality results and allows more configuring than the original
DivX 5 codec. It can even automaticly reduce post-processing if your CPU
is getting overloaded. The noise filter adds a kind of a rasterising
effect to the picture - might be useful in some cases. The alpha version
also includes experimental playback for MPEG-1 and MPEG-2 files (such
as VCD and SVCD movies), which works pretty damn well. Only problem is
that MPEG-2 playback can't play the SVCD clips directly from the CD, but
requires the video to be extracted to the HDD by using VCDGear first.
